JAMES C. MOCK, 013 DETROIT, MICHIGAN;

RAIL-JOINT.

To all whom it may concern 7 Be it known that I, JAMES 0. Moon, acitizen of the United States, and residing at Detroit, in the'county ofWayne and State of Michigan, have invented a new and ImprovedRail-Joint, of which the following is a specification.

This invention relates to means for connecting adjacent endsof railwayrailsin such a manner that while these ends will be held insubstantially perfect alinement, they will be insulated fromeach other.

This invention consists, in combination with the rail-ends and sheets ofinsulating material surrounding these ends, of fishplates fittingbetween the heads and bases of the rail-ends and having central portionsextending below said bases, and adjustable wedges'adapted to be drawninto the spaces between the lower sides of the bases of said rail-endsand the extensions on the fishplates to secure the parts together.

In the accompanying drawing, Figure 1 is an elevation of a rail-j ointin position. Fig. 2 is a view showing a rail and one fish-plate insection on the line 22 of Fig. 1, and another fish-plate inendelevation. Fig. 3 is anend elevation of a fish-plate. Fig. 4. is a sideelevation of a wedge. Fig. 5 is a section on the line 5-5 of Fig. 1.

Similar reference characters refer to like parts throughout the severalviews.

The rails 1 and 2 shown are of usual design and are separated by a sheet3 of hard insulating material such as rubber, guttapercha, vulcanite,fiber board or any other desirable substitute therefor. .Other sheets 4and 5 of hard insulating material extend along below the rail heads 6,down alongside of the webs 7, out above the bases 8 and around the edgesthereof and inwardly below said bases. The portion extending be-- lowthe bases need not be the full length of the main portions of thefish-plates as the lower portions of these members are of less length.

The two fish-plates 9 extend along between the heads and bases of therail-ends, being beveled so that where the fish-plates are drawn towardeach other by means of the bolts 10, the union between them and therail-ends will be very rigid. Sleeves 12 of insulating material areshown on the bolts while other sleeves 13 within the holes in thefish-plates add additional security. Squares 14: of insulating materialare slipped onto Specification of Letters Patent.

Application filed January 26, 1916. Serial No. 74,299.

through the lugs 24 formed on the wedges 25 that lie between theextensions 18 and the bases of the rails. When drawn outwardly thesewedges force the bases of the adjacent ends of the rails up against theyertical portions of the fish-plates and thus insure a very rigid joint.These bolts 23 and wedges 25 are positioned before the fishplates areapplied to the rails, and after the fish-plates arev secured inposition, the wedges are drawn outwardly to lock the parts together andto give positive support to the adjacent ends of the rails. Bythe use ofthese wedges, the slight movements between rail-ends inherent in allrail-chairs is avoided. The extensions 18 and wedges 25 need not be aslong as the main portions of the fish-plates and therefore do notnecessitate a great deal of cutting of the crossties. One bolt 23 may befound sufiicient for each wedge 25.

The proportions and details of the parts may all be changed to conformto varying requirements Without departing from the spirit of myinvention.

I claim 1. In a rail joint, the combination of the abutting rail endsand the fish-plates, projections on the fish-plates having inclinedfaces extending under the rails, a wedge interposed between and bearingagainst each of said faces and the bottom of the ends of said rails, and.a bolt projecting from each wedge through the projection on the fish-'passing through the fish-plates and the rail ends, projections on thefish-plateshaving projection on the fish-plate which said wedge engages,

74:. 'A rail jointcomprising fish-plates and the interposed rail ends,projections on the fish-plates having inclined faces extending under therails, a transverse wedge interposed between and bearing against each ofsaid faces and the bottom of the ends of said rails, and means to forcethe wedges away from each other for the purpose specified.

V -5. Arail joint comprising fish plates and interposed rail pends,bolts passing through the fish plates and the rail ends, projections on.the fish plates having inwardly and downwardly inclined faces extendingunder the rails, wedges interposed between the inclined faces and bottomof the rails, and means toforce the wedges away from each other,substantially as described.

6. A rail joint comprising fish plates and interposed rail ends, boltspassing through the fish plates and the interposed rail ends,projections on the fish plates having in wardly and downwardly inclinedfaces extending under the rails, wedges interposed between the rails andthe, projections on the fish plates, and means to force said wedges awayfrom each other, substantially as described.

- tions onthe fish plate it engages substan wardly and inwardly inclinedfaces extending under the rails, wedges interposed between the bottomsof the rails and the projectionsvon the fish plates, and boltsprojecting from one wedge through the projectially as described.

8. In arail joint, the combination of: the

abutting rail ends and the fish-plates, insulating materialseparatingthe rail ends from each other and the fish-plates, projections on thefish-plates having inclined faces extending under the rails, a wedgeinterposed between and bearing against each of said faces and the bottomof the ends of said rails, and a bolt projecting from each wedge throughthe projection on the fish-plate with which it engages.

9. In a rail joint, the combination of the abutting rail ends and thefish-plates fitting the same, sheets of insulating material between therail ends and the fish-plates, bolts passing through the fish-plates-andthe rail ends, projections on the fish-plates having inclined facesextending under the rails, a

wedge interposed between and bearing against each of said faces and thebottom of the ends ofthe rails, anda bolt projecting from each wedgethrough the projection on the fish-plate with which it engages.

10. In a rail joint, the combination of the abutting rail ends and thefislrplates, insulating material between the abutting rail ends andbetween these rail ends and the fish-plates, bolts passing through thefishplates and the rail ends, projections on the fish-plates havinginclined faces extending under the rails, a wedge interposed between andbearing against each of said faces and the bottom of the ends of saidrails, and bolts projecting from each wedge through the wedge andprojection on the fish-plate which said wedge engages.

11. A rail joint comprising fislrplates and the interposed rail ends,sheets of insulating material between the fish-plates and rail ends,projections on the fish-plates having inclined faces extending under therails, a transverse wedge interposed between and bearing against each ofsaid faces and the bottom of the ends of said rails, and means to forcethe wedges away from each other for the purpose specified.

In testimony whereof I sign this specification.
